GANG-PLOW.

SPECIFICATION forming part of Letters Patent No. 352,196, dated November 9, 1886.

Application filed June 16, 1884. Serial No. 135,013; (No model.)

To all whom it may concern:

Be it known that I, FRANK F. LANDIS, a citizen of the United States, residing at lVaynesborough, in the county of Franklin and State of Pennsylvania, have invented certain new and useful Improvements in Gang-Flows, of

which the following is a specification, reference being had therein to the accompanying drawings. a V

This invention relates to gang-plows, and has reference more particularly to the means employed for connecting the gang ofplows to a traction-engine or other similar motor; and one of the principal objects of the invention is to connect the gang to the axle of the" motor in such a manner that the plowing mechanism shall always be maintained at a height from the ground corresponding with the axle,while at the same time the body of the motor shall be capable of vertically oscillating on the axle, r

plow sufficient in extent to clearly illustrate,

myinvention. Fig. 5 is an enlarged detail of the adjustable suspension-link and its adjuncts.

Like letters indicate like parts in all the figures.

With the axle Athe motor B is connected in any suitable well-known manner, and the the builder. The gang-plow frame comprises a straight same choice and arrangement in regard to the manner of connection of the drivers 0 to the axle is left to the judgment and discretion of draft-beam, D, and diagonal gang-beam E, and a transverse draft beam, F, connecting the straight and diagonal beams and arranged at the rear of and near the motor. The rear end of the straight and diagonal draft-beams are unitedin the casting E, adapted to receive said ends and tobe secured thereto, and also adapted to receive the spindle of a caster, E The straight draft-beam is extended toward and terminates at apoint directly beneath the projecting end of the axle, and is adapted to be connected to the axle by a suspensionlink, G, which may be of any suitable construction, which admits of its adjustment to the axle and to the draftbeam, and which is also preferably adapted to support the said beam at a distance below the axle. A preferable form of said link is illustrated in Fig. 5, and is hereinafter described, although I wish it understood that I do not limit my invention to any form of suspensionlink, as the beams D and E may be curved upwardly and mounted directly on the nate at and below the axle A, (see Figs. 2, 4, and

5,) which is itself also extended outward from the drivers 0, either in a single continuous piece (see dotted lines, Fig. 1) or with an extension piece or bearing held by the brace O at such a distance as to terminate above the ends of the said gang-beams, in which case suspensionlinks G are employed in order to support the gang-beams at a desired distance below the axle. When the axle is continuously extended beyond the traction-wheel G, the braces G extend from the tire to a collar or flange, G, mounted upon an extension of the axle, so that the said extension is strengthened against deflection from a right line.

By the construction thus far described Ihave provided means whereby the frame of the gang-plow is supported at a desired distance from the ground, and such a distance is maintained without regard to any oscillations of the body of the motor B, because as the traction-wheels follow the undulations of the ground the gang-beams, with or without the suspension-links, as a matter of course must follow the axle and wheels.

Now, it remains to provide draft devices of draft-rods, F, which in this instance are connected to a series of eyebolts, F by a rod, F, said eyebolt being passed horizontally through the draft-beam F. The opposite ends of the bars are gathered in a short bar, F, from the front ends of which extend radiusbars F", adapted by means of a turn-buckle or other suitable device to be adjustable lengthwise, which radius-bars are connected in any suitable manner to the motor. The short bar F (see Fig. 3) is connected to the lower ends of the bolts H, which bind the box I of the axle, the frame J, (shown in dotted lines,) and the cushioningsprings K and their upper and lower stirrups L together, so that the connecting-link from the transverse bar F to the motor B comprises the bars F, the short bar F, and the radius-bars F together with any suitable means for connecting the said radius-bars to the motor-as, for example, the bracket F, secured to the boiler-frame for supporting the said boiler, to which bracket, by means of a bolt or bolts, F, the radius-bars F are secured. Said radiusbars may be secured to any suitable part of the motor, and I do not limit my invention to the exact means of either connection just described. Now, it will be observed that the oscillations of the motor are absorbed by means of the pivotal connection of the radiusbars or draft-bars with the motor. the transverse draft-beam, and the short bar, and by the cushioning-springs K, and that the pivotal action of the parts upon each other bet-ween the points of attachment F F of the radius and draft bars, V

respectively, serves the purpose in viewmainly to permit a direct attachment of the gang-frame and the motor for draft purposes, which shall at the same time conform to the work satisfactorily in connection with the di rect connection of said frame with the axle to secure uniformity of distance of said frame to the ground at all times.

A very important advantage is now readily apparent, in that the line of draft is central and extended completely across the gang-frame, and Ideem it proper to state at this point of the description that the diagonal and straight beams of the gang-frame may be directly connected to the ends of the axle, and thus insure the same advantage of uniformity of distance from the ground, and in sucha construction the links Gwould be dispensed with and an equivalent thereof would be provided, the eyebolts 15 or their equivalents would be extended vertically through and to a sufiieient distance above the upper surface of the transverse draft-beam F to permit of adesirable connection of the draftbars therewith; but in view of the fact that the most desirable diameter of a traction-wheel is such as to bring the gang-frame at too high an elevation from the ground if directly connected therewith, I prefer the construction shown and more particularly described, and even the objection just mentioned may be overcome in a great measure by curving the front ends of the straight and diagonal beams of the gangframe upwardly and connecting them directly with the axle, instead of employing a suspension-link.

The preferred snspensioirlink G is shown clearlyin Fig. 5, where the drai'tbarD is provided with a casting, D, comprising a vertically-slotted lug perforated horizontally, as at D to receive the end of the link G, which is provided with a series of holes, 9, whereby the gang-beam may be secured upon the link at different points of elevation. The upper portion of the link is bifurcated to form bolts G, which pass through a bearing-block, G", mounted upon the extension of the axle, and are provided with nuts G", resting upon the upper surface of the bearing-block, whereby further adjustment may be made by turning said nuts. A nut and washer, G, or an ordinary pin, G", may be employed to retain the beams or the bearing-blocks of the link against removal from ends or extensions of the axle. If desired, the connection of the front end of the bars F may be directly with the motor or directly with the axle-that is to say, the radius-bars may be dispensed with; but the principal object of the radius-bars being to retain the proper relation of the front end of the draft-bars to the motor, I prefer to retain said radius-bars. It is clear that the draft-bars F may be pivotally secured to the axle or directly to the motor in such manner as to prevent lateral spreading of said draft-bar, and that that portion of the axle within the braces and the driver 0 (see dotted lines, Fig. 1) may be dispenscdwith, said braces, collar, and the outwardly-projecting portions or extension of the axle alone serving as. a bearing for the diagonal gang-draft beam, whether directly attached thereto or suspended therefrom by a link.

Having described my invention and its operation, what I claim is 1. The combination of the traction-wheels and axle of a motor with a gang-plow frame having diagonal and straight draft-beams,said beams extended to points outside of said traction wheels upon a Vertical plane passing through the axle of said motor, with gangframe draft-bars pivotally connected to the gang-frame and to the axle, substantially as described.
